Unique vintage mug with a very spiffy portrait of a gentleman with handlebar mustache, bowtie and top hat named Bob. Hand painted all around. Has an opening for spoon to keep it from slipping around the cup when drinking. Has initials M. H. (Mildred Hinas?) 1983 carved on the bottom. Has a couple of chips on the lip of the cup.
